• Fuel enters the fuel pump at the top of the vapor separator swirl chamber where it is centrifuged, separating the liquid from fuel vapors.
• Liquid fuel is forced through the fuel pump inlet vanes which create the necessary differential pressure required to draw fuel into the pump inlet and expel pressurized fuel through the pump outlet.
• Fuel vapors separated in the swirl chamber return to the aircraft fuel tank.

OIL SYSTEM
• As oil enters the oil cooler, it will flow in one of two directions:
• (a) When the oil is cold, the oil temperature control valve (vernatherm) will open and most of the oil will bypass the cooler. Some oil always flows through the cooler to help prevent congealing in cold weather.
(b) As the oil warms, the oil temperature control valve actuates to close off the cooler bypass, forcing oil flow through the cooler core. In operation, the oil temperature control valve modulates to maintain oil
